Burnley have only been able to add to their squad so far this summer with Charlton Athletic pair Johann Berg Gudmundsson and Nick Pope, for an estimated intial outlay of £3.6m.

The club have had three offers for both Derby County’s Jeff Hendrick and Dale Stephens of Brighton knocked back, as they look to bolster the midfield in particular.

And with just over a fortnight to the opening game of the Premier League season against Swansea City, Burnley are struggling to make inroads into spending their share of a record television deal.

Dyche is pinning his hopes for new faces on chairman Mike Garlick and his board of directors, as he said last week: “I have told them the targets we want and it’s down to them now.”

Not much has changed in the intervening days, as Dyche explained: “We know who the players are, it’s doing the deals.

“That’s for the chairman to get on and do. The market is challenging. I’m a broken record, but it’s the truth.

“It’s not just us, when you see the numbers flying around, it is a big challenge.”

Sunderland have yet to add to their squad, while Hull City – without a manager after the departure of Steve Bruce – have only been able to sign Will Mannion from AFC Wimbledon.

At the other end of the market, record sums are being spent, and Dyche noted: “There’s certain clubs spending a lot of money, which is probably surprising in another way when people see the amounts on certain players, then there are others who are sitting tight and keeping their cards close to their chest.

“We’re in the middle somewhere, trying to get deals done which we think are appropriate.

There are quite strict guidelines here as to what the board and the club want to do financially, and it’s very tough.

“I made it clear last time we were here, I made it clear this time and I made it clear in the Championship, it’s a club that has to be run properly, and that’s how the board want it, and it makes it very challenging, it’s as simple as that.”

There is no loan window either to ease the burden, as he added: “They keep changing these rules. Especially considering young player development, I don’t know how that’s going to help them.”
